从BLOB生成图像的问题

Question

I've been struggling with this for a while now. I just can't generate an image from blob field on my DB.

This is my whole code:

<?php require_once('db.php'); ?>
<?php
    @mysql_select_db($db_login, $login);

    $query_consulta_fotos = "select `foto01_NmArquivo`, `foto01_Descricao`, `foto01_Arquivo`, `foto01_Tipo`, `foto01_Tamanho` from equipamentos where id = 2";
    $result = @mysql_query($query_consulta_fotos);

    $data = @mysql_result($result,0,"foto01_Arquivo");
    $type = @mysql_result($result,0,"foto01_Tipo");

    Header( "Content-type: $type");    

    $size = 150;  // new image width
    $src = imagecreatefromstring($data); 
    $width = imagesx($src);
    $height = imagesy($src);
    $aspect_ratio = $height/$width;

    if ($width <= $size) {
      $new_w = $width;
      $new_h = $height;
    } else {
      $new_w = $size;
      $new_h = abs($new_w * $aspect_ratio);
    }

    $img = imagecreatetruecolor($new_w,$new_h); 
    imagecopyresized($img,$src,0,0,0,0,$new_w,$new_h,$width,$height);

    // determine image type and send it to the client    
    if ($type == "image/pjpeg") {    
      imagejpeg($img); 
    } else if ($type == "image/x-png") {
      imagepng($img);
    } else if ($type == "image/gif") {
      imagegif($img);
    }
    imagedestroy($img); 

mysql_free_result($consulta_fotos);
?>

If I echo $data and $type I get the whole char chain and the file's MIME respectively and everything seems fine.

Any help is appreciated.

Thanks!
